In addition, this item may be used by data structures in other ITS standards.
Remarks: Note: May want to add bread crumbs to end of this message (optional).
5.7 Message: MSG_MapData (GID Layer)
Use: The MapData message is used as wrapper object to relates all the types of maps defined in the
standard. This includes such items as complex intersection descriptions (used with the SPAT message),
high speed curve outlines (used in curve safety alerts), and segment of roadway (used in platoon
applications). The contents of this message are at time informally referred to as the GID layer.
